Hi ...
	i need some help in interfacing C and Ada. :):)  what i need is to call
an Ada procedure from a C program.
i opposite of this, i realize, can be done using the pragma INTERFACE... 

	specifically i need help in the following...

	- can this be done at all... ?
	- is there any limitation(s) on this kind of interface in terms of
	parameters to procedures etc.
	- what kind of performance lags... r experienced. 
	
	i am using the gcc v2.4 on sun sparcstation running SunOS 5.x for C
as for Ada we have DACS and the Alsys compilers.

	any pointers/tips would be appreciated...

thanks!

Harmel.
